WINDOW-CURTAIN FIXTURE.

SPECIFICATION forming part of Letters Patent No. 543,946, dated August6, 1895.

Application filed May 23, 1895. Serial No. 5501 (No model.)

To all whom it may concern.-

Be it known that I, EDWIN 1. PYLE, a citihem of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in WindowCurtain Fixtures; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements inwindow-curtain fixtures; and it has for its object to provide fixturesof such a nature that the curtain may be lowered from the top of thewindow at will, so as to admit of proper ventilation, and also toprevent any rattling that may be caused by a strong draft through theWindow.

A further object of my invention is to provide a simple and effectivedevice whereby the belt or adjusting-cord to which the curtain-roller issecured may be kept taut, so that the proper working of said cord isassured; and with these ends in view my invention consists in thevarious details of construction hereinafter described.

In the accompanying drawings, which form a part of this specification,Figure 1 is an interior perspective view of a window equipped Figs. 2and 3 are detail elevations'of the bearings for the ends of thecurtain-roller; Fig. 4, a section on the linex 0c of Fig.2; and Fig. 5ahorizontal sectional view of a window-casin g, showing the groovedguideways in cross-section.

Similar numbers of reference indicate like parts in the several figuresof the drawings.

1 is the window-casing, to the upper part of which is secured two doublepulleys 2, (but one shown,) and 3 are two single pulleys, (but oneshown,) which are secured at either side of .said casing near the bottomthereof.

4 is the adj usting-cord which passes around the pulleys after themanner of an endless belt, and is crossed at the top of the casingclearly shown in Fig. 4. The other ends of the cord are passed througheyes 8 in the ends of the swivels 9, which are secured to the lower partof the fixtures. One of tho fixtures 5 is provided with a keyhole-shapedaperture 10, as shown in Fig. 3, within which is inserted a headedjournal (not shown) on one end of the curtain-roller. has a verticalslot 11, within which is inserted the flattened end of the spring-rod(not shown) of an ordinary spring-roller curtain, and is securely heldwithin this slot by means of the set-screw 13.

Since both of the fixtures or bearings are exactly alike, with theexception of the shape The other fixture of the slots within which theends of the curtain-roller are journaled, as previously described, Ishall hereinafter only refer to one of these fixtures in describing theother elements of the same.

Referring particularly to Fig. 4, 1a is an antifriction-roller journaledbetween ears 15 (but one shown) rigid with the back of the bearing, 5.16 is a rubber tire on said roller. 17 is a screw depending from thebearing'5, and 18 is a nut run thereon. 19 is an annular groove in thenut 18, and 20 is a tubular swivel having its upper portion formed intoan annular flange 21, which fits within said annular groove 19 andserves to connect the nut and swivel together in such manner that saidnut may be rotated independent of the swivel.

22 is a strip of wood or other material socured to the top of the casing1, and 23 is a vertical groove or guideway in said strip, within whichthe roller 14 tracks, as shown in Figs. 1 and 5. By thus guiding themovements of the bearings for the curtain-roller and providing theantifrietion-roller l twith a rubber tire or buffer all unnecessarynoise and rattling is done away with, especially the annoying rattlecaused by a strong draft when the window has been opened at the top forthe purposes of ventilation.

When the adj usting-cord has become loosefrom any cause it may bequickly and effectually tightened without inconvenience by sim plyturning the nuts 18.

I am aware that curtain-fixtures have been heretofore provided withmeans for lowering the curtain-roller from the top of the window to anydesired plane, and I therefore do not claim this feature; but

What I do claim, and desire to secure by Letters Patent, is-

5 In curtain fixtures of the character de scribed, the combination ofthe adjusting cord, the pulleys around which said cord is passed, thebearings carried by said cord and in which the curtain roller isjournaled, the

[0 screws depending from said bearings, the adjusting nuts on saidscrews provided with annular grooves, the swivels provided at one endwith an eye and at the other end with an internal annular flange whichengage the annular grooves on the adjusting nuts, substantially as andfor the purpose described.

In testimony whereof I afiix my signature in presence of two witnesses.
